Subject: NDDriverStdArrays problem with configuration

Hi all,

 

I have a problem with the proper configuration of NDDriverStdArrays areaDetector driver.

To test my settings, I have prepared IOC which contains NDDriverStdArrays driver and NDStdArrays plugin.

To caput picture 1236x1236 as a waveform I am using quick python script:

 

#!/usr/bin/env python

import epics

import numpy as np

import time

while(1):

  for x in range(17):

     data="">

    pv=epics.PV('TEST:ArrayIn')

    pv.put(data)

    time.sleep(1)

 

 

However, I am receiving following error:

 

2017/04/10 19:46:38.422 NDDriverStdArrays:writeXXXArray: error allocating raw buffer

2017/04/10 19:46:38.422 TEST:ArrayIn devAsynInt16Array::callbackWfOut write error

 

It looks like my settings are incorrect somewhere. Has anyone encountered this problem before?

Full st.cmd below.

 

Many thanks,

Marcin
